There are an enormous amount of rumors flying around, particularly in light of FUNimation’s strange rap music for the series: Dragon Ball GT‘s earlier episodes will be released later as part of Dragon Ball Z, they are not doing the earlier episodes at all, their site starts with episode summaries around episode fifteen, etc.
Special thanks to Derek Smith for passing along this link to the first volume of DBGT on DVD at RightStuf — the description definitely describes the first episode of the series. However, Rild (the blue character on the front) absolutely does not show up the first 62 minutes of the series. Correct description, incorrect representation? More to come on this one, for sure.
